`IMPROVEDvTOE-CALKIN FOR HORSESHOES.

Specification forming part of Letters Patent No. 31,995, dated April 9,1861.

T0 @ZZ whom, it may concern.:

Be it known that I, CHARLES H. PERKINs, of the city and county of Providence, in the State of Rhode Island, have invented a new and useful Improvement in the Toe-Calkins for Horseshoes; and I do hereby declare that the following specification, taken in connection with the drawings making a part of the same,

is afull, clear, and exact description thereof.

Figures 4 and 5 are views of a toe-calkin` as I haveimproved it. Figs. l and 3 are views of the same when welded to thetoe of the shoe.

Itis a fact well known to all farriers `who are accustomed to shoe horses that particularly during the winter months, in climates where the ground is frozen, the toe-calkins of horseshoes are broken off` long before the shoe re quires resetting. This is occasioned by the fact that as toe-calkins are usually made a perfect welding between the calkin and the shoe is the exception rather than the rule, no

other means for attaching the two together inV is, in addition to the welded joint, mechanically held to the shoe in such a manner and at such a point that'thechance of its being broken off is almost entirely removed.

A, Fig.`5, represents a calkin of steel. At

equal distances from the two extremitiessay about one-fourth of an inch apart-I make two projecting steel points, b b. The calkin is applied to the shoe in the usual way and the two at the points of contact brought to a welding heat. As soon as the shoe cools, it will be found that the tapering steel points b b, from the en'ect of the blows of the hammer, as well as from unequal contraetiomhave been crooked like the roots of a tooth,'Figs. 3 and l, and

thereby greatly assist the welded joint.

Another and important advantage which is the result of my improvement consists in theA fact that the steel points b b are located in the most favorable position for resisting the shock sustained by the shoe at each step of the animal, the percussion serving rather to tighten. the spurs than to unloose the calkin, as is the case with the common fastening.

Instead of two spurs or projections, as shown in Fig. 5, a singlespur placed midway between the extremities may be used, as shown in Fig.

4. This, though possessinggreat advantages j over the common calkin, is considerably in-` ferior to the one above described.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

rPhe improved toe calkin described, consisting `of a steel piece, A, provided with one or more tapering steel spurs, b b, placed midway between the two extremities, or nearly so, forthe purposes described, the improved article being substantially such as specified- In testimony whereof I have hereunto Set my name.
